Upgrading parts in iMacs

Upgrading hard drive and ram are never easy on iMac, as iMac is just a power-packed machine with large screen. Thus everything is just packed so tightly and neat. But 2011 iMacs make upgrading Hard disk in your iMac even harder as Apple have change the SATA connector from a 4-pins to a 7-pins. This helps Apple’s firmware to control the fans for the drive temperature, but due to that when you upgrade hard disk yourselve, the disk will spin out of control, as the firmware will not control the fan speed anymore.
